Abstract：Toefectivelyobtaintheparameters toreflecttheprocessofwatermovementinsoil，ahydrodynamicparameterinvesion model wasproposedbasedonanimprovdbuterflyoptimizationalgorithm（IBOA）.Buildinguponthetheoreticalframeworkofsoilwatermovementquations，firstly，thebuterflyoptimizationalgoritm（BOA）wasusedtofindtheoptimalsolutionthroughthecombinationof globalsearchandlocalsearch，andtheswitchingprobabilityintheBOAwasobtainedthroughtherandomwalkalgorithm，o astoimprovethesituationthatthealgorithmwaseasytofallintothelocaloptimum.Secondly，theimprovedalgorithmasaplidto thedataundertheconditionsofusingHYDRUS-1Dtosimulatetheunifordistributionofunsaturatedsoilmoistureintheinitialwater content.Atlast，theappropriateobjectivefunctionasselectedandtheimprovedbuterflyotimizationalgorithmwasusedfornver sion.Theresultsshowedthattheaveragerelativeerorofteparameterinversionvalueoftheimprovebuterflyoptimizationalgoritm was 0.22% 2 3.60% ，which could better invert soilhydrodynamic parameters.The improved butterflyoptimization algorithm could ffectively improve the accuracy of the estimated parameters and obtain high-quality global optimal solutions.
